Why do I get NSIS Error
From NSIS Wiki
If you are reaching this page from an error message, you are having a problem installing a program. The downloaded file is either incomplete or modified from the original file. While this page will outline basic solutions:
Please contact the publisher or developer of the program you are installing for complete support.
What does this message mean?
The installer has failed a self-check. This means that for some actions, the installer file has been altered from its original form. If the install were to continue, the software install would not be complete and will be broken. To prevent further problems, the installer refused to continue.
How do I fix the problem?
There are a number of ways the installer can be modified, but we'll cover steps to fix the problem on your end. If all these steps don't work, please contact the developers or publishers of the software you are attempting to install or your normal computer support channels.
If the software was obtained from the Internet
Clear your browser's cache.
Disable any download accelerators or managers and download the installer again.
Rename the installer so it is a simple one-word name with no special characters (without removing the .exe suffix)
Example: install.exe
Download the installer from another source approved by the software developer or publisher.
It might be corrupted on the server, or the connection to the server is unreliable from your location.
Update your anti-virus software (if installed) and download the installer again.

Disable your anti-virus software and download the installer again.
Download the installer using another computer and copy it to the original computer.
If you have the nVidia firewall installed, uninstall the program and download the installer again.
Scan for, and remove malware and viruses on your system.
Scan the hard drive using scandisk, chkdsk, or any other hard drive repair tool.
If the software was obtained from a CD, DVD, or other physical media:
If you are receiving this problem from an installer located on a disc or other media besides the Internet, then the problem may be due to a hardware failure or more likely the physical media being damaged. Try reading files from other parts of the media. If you are receiving read errors with other files on the disc, then the problem is likely due to damaged media. You will need to contact the source of the physical media for a replacement.
Final Options
As a last resort, the installer can be executed even though it's corrupted. To bypass the corruption test, pass /NCRC on the command line. To do so, go to Start->Run, type cmd and hit Enter. A black console window should open. Drag the installer into the window, hit Space and type /NCRC. Hit Enter again and the installer should start. This is not recommended!
When all else fails, you will need to contact either the developers of the software you're attempting to download or your personal computer support channels.
Why can't NSIS help me?
NSIS developed the "envelope" that contains the software you are attempting to install, not the software itself. NSIS is an open-source community that develops the software which installs software. This allows any software developer, including you, to use NSIS to ease the process of installing software. The problems you are having involve an outside party modifying the installer and is beyond NSIS' control.

Bold textWhat does it mean when it says "It may be possible to skip this check using the NCRC -- it means that if you run the installer as install.exe /NCRC that it will bypass the check for corruption.

[edit] NSIS error and NO real solution!!
What a pity that nobody wants to realy get rid of that big issiue! It's a nuisance and lots of people to whom I recommended OO2 called me and said they are also not able to install OO2. So they switched back to MS-Office. Is it that difficult to give a clear work around?
The instruction read like the MS knowledge base. NOT real knowledge! Just try. If you're lucky it'l work. grrrrrrrr
How about asking for help, like this guy? I don't recall seeing you on the forums with details that say "I want a solution" instead of "I want to complain". --kichik 04:37, 30 July 2006 (PDT)
[edit] NSIS Error Fix
I had the NSIS error ever since I downloaded IE7. I had the Google toolbar with IE6 but it didn't come through on IE7. I reinstalled Google toolbar from this link http://www.java.com/en/download/manual.jsp as well as installed the latest version of JAVA for Windows/online. The error is gone!!!
[edit] another problem
This error appears to me when I open a web link. It happens in different sites (eg. ebay). What can i do?
